On the other hand --- I just upgraded one of my CentOS7 systems to
3.10.0-1160.80.1 today. With that kernel it will not run any KVM guest.
The system hangs - HARD - within one or two seconds of issuing the
"virsh start ..." command. It hangs so hard that a power-off restart
using the back panel switch is required. It does not log any error I
can find, nor display any message about a kernel panic.
Rebooting with 3.10.0-1160.76.1 works fine.
The system is an older SuperMicro mainboard with a Q9400 processor.

Is anyone else experiencing trouble with

I'm seeing a kernel panics in the kvm module on one of
our VM hosts with
it.
I did notice a new libvirt update as well, but it seems
to work fine with
the
older kernel (.76.1).
Where did you get the .80.1 kernel from? I'm a bit confused
because I can
only see .76.1 on my systems.

I'm actually running Scientific Linux, which seems to be a little
ahead here.
Probably not related, but vmlinuz-4.18.0-372.32.1.el8_6.x86_64
(AlmaLinux 8.6) had a kernel panic on a Intel Xeon E5504 processor,
but works fine on Xeon E56XX processors (5620 specifically in our
tests). * Believe from kernel version, the original email is for
Centos 7, possible the same change that went into the EL8 kernel went
also to EL7 Triggered right after I used virsh start to start the vm.
(Caused Black Screen, and reboot. Found this in the crashed kernel
logs on /var/crash) Works fine on
vmlinuz-4.18.0-372.26.1.el8_6.x86_64 and
vmlinuz-4.18.0-372.16.1.el8_6.x86_64
In fact, related - on our systems attempt to start qemu-kvm VM under
kernel-3.10.0-1160.80.1.el7.x86_64 freezes any of 5 workstations with
dual E5507 (all worked OK under kernel-3.10.0-1160.76.1.el7.x86_64 and
any previous version). The workstations with E5-2609, E5-2650 or
E5-2630 are not affected - all of them run qemu-kvm VM under
kernel-3.10.0-1160.80.1.el7.x86_64 without problems.
Thankfully, no problems with 2x Xeon E5-2667 v2 and CentOS 7.9 kernel
3.10.0-1160.80.1.el7.x86_64.
